Solid waste refers to the production, life and other events resulting in loss of original use value or did not lose value but abandoned or given up solid, semi-solid and placed in a container of gas objects, physical as well as legal and administrative regulations items of solid waste management, materials. Through different physical, chemical, biological and other methods, the solid waste into easy to transport, storage, use and final disposal morphological structure of the process. Here we take a look at using physical methods of pre-treatment of solid wastes. 1. Crushing The use of force to overcome the cohesion between the particles of solid waste leaving split into small chunks of solid waste in the process. 2. Cryogenic crushing At room temperature it is difficult to break solid waste time-varying low temperature embrittlement properties can make broken methods. At the same time, based on different material embrittlement temperature can be selectively broken. 3. Wet crushing 4. Magnetic hydro separation (MHS) 5. Magnetic hydro dynamic separation (MHDS) 6. Magnetic hydro static separation (MHSS) See more details, please view the article:Pretreatment of Solid Waste
